When the strings vibrate, the pickup generates audio and electrical signals similar to the strings vibration. This volume electric signal can be directly input into the power amplifier to promote the sound of the speaker, or can be processed by the effector and then input into the power amplifier. Electric guitar Fruit Device is an electronic instrument specially used to process audio and electrical signals produced by electric guitar. It can make electrical signals deform in many ways and change the sound effect of guitar audibly. The production of the effector makes the sound of the guitar not only have a strong and strong aesthetic feeling, but also have the power to shock people. There are many kinds of effectors, such as “delay”, “distortion”, “harmony” and “balance”.
